Abstract

PURPOSE: To reduce an editing gap and to attain high density recording.
CONSTITUTION: On a rewritable disk 10, a preformatted encoding pattern area 22 for obtaining eccentricity information at the time of chucking a disk, is provided. At the time of driving the disk, the eccentricity information at the time of chucking the disk is detected from a reference pulse obtained by reproducing an encoding pattern 22, and based on the eccentricity information, the frequency of a data writing or reading clock is modulated corresponding to the eccentric position. Accordingly, the data can be surely written in a sector 16 even by eccentricity chucking. Thus, it is enough just by taking several clocks of an editing gap 18, and the rate posessed by the editing gap in the entire disk can be minimized and the high density recording can be obtained.
